Watchcase, that is, a Watchcase which will not perni under anyconditions ot use, the penetration of Water to the watch move ment,attention is necessarily given', not only to the closures of the case,but to the sealing of the case about the usual Winding and settingarbor. The present invention has for its object to provide improvedmeans for scaling a Watch eiiectuall7 against the penetration ofmoisture about the winding and setting arbor, but Without preventing theproper performance oi the usual functions or such arbor. Provision ismade whereby arbor can be sealed under sufficient pressure to preventabsolutelyr the admission of Water but can be relieved readily :frompressure to permit it to be rotated for the purpose of WindingP thewatch or to be pulled out and rotated for the purpose of setting thewatch. The invention will be more fully explained hereinafter withreference to the accompanying drawing in which the inven tion isillustrated as embodied in convenient practical structures and inWhich,- Figure l is a detail View in section through the crown of aWatch, with a portion of the Watchcase center, the Winding and settinglarbor being shown in elevation.

and receives centrally therein the usual arbor or spindle c Which servesto transmit the rotary motion o'f the crown al to the Winding andsettingmechanisms, through devices oit' any usual or suitableconstruction. The arbor is shown to be provided as usual with taperedshoulders c for cooperation With a spring detent c2. A suitable packingWasher a may be placed between the outer end of the. pendant sleeve ZFand the inner side olf the chambercd crown al. The crown is securedxedly upon the arbor or spindle 0. Also secured iixedlv to the crown aiis a skirt e, which is preferably flanged as at e so as' 70 to overlapthe reduced outer portion of the base of the pendant the skirt.preferably being' conical exteriorly, -as indicated at e2. The base ofthe pendant and the under side of the skirt e are so proportioned as tor ceive between them, when in assembled relat-ion, a compressible Washerof any suitable material, preferably saturated. with oil or some otherWater repellent. The upper side of the base oi2 the pendant l) is annuularly groovcd. as at 133. to receive a surplus of the oil with which theaching f is saturated and to al'ord a space for iioivage of the packingyunder pressure. and the under side of the shirt c is provided with asimilar annular recess e3 for a like purpose.

. Fitted upon the skirt e is a cap g which is screw-threaded interiorly.as at g, to engage the threaded portion o of the pendant. Exteriorly thecap g2 is lrnurled, or similarly formed, as at (f3. so that it may begrasped firmly b v the lingers.

`Vifhen the Watch'is in use the cap g is screwed down upon the pendant.This 'acnialres a close contact between the under side of the cap andthe upper. conical surface of. the shirt. but it causes the packing f tobe compressed bet-Ween the under side of the shirt the base of thependant and also the packing- Z to be com pressed between the upper oi?the pendant sleeve b2 and the under side of the croivn d'. The passanoof moisture from Without into the central bore the pendant is therefore'electualljv prevented This turningA of the cap to prevent access ofrnoisture prevents the outward movement of the arbor c or setting;- andalso there-tation oi the arbor for Winding. To permit the crown to berotated 'for Winding'` the cap is backed oit slightly and to permit thearbor to be pulledvout and rotated for setting' the cap flic as 'incassawith the arbor.

, @bviously the screw-threaded engagement voi: the cap with thependant-base might be replaced by an engagement of the cap with thewatchcasev center, as indicated in Figs. 6 and 7 in which the cap g isshown as formed with a flange g3 which is slotted in its eri iherv as att for co )eration with undercut lugs c secured to the watchcase centera. The upper surface of the iiangc g may be inclined circun'iferentiailvso that when it is engaged with 'the undercut lugs c" and located itwill draw the parts into close contact.

lt will be understood that details of construction .may be varied tosuit diderent requirements ot use without departing from. the spirit ofthe invention as the same is set forth in the accompanying claims.

It is to be noted'rthat the skirt of the crown houses'the outer end ofthe pendant, and that a nioisturetight ljoinit is produced by mydescribed construction between the skirt and the pendant, at theexterior oi the latter and distant from its open outer end, that is tosay, between said outer end and the base of the pendant. Thus, there isno possibility ci water reaching the outer end of the iendant to colleotthere and enter the pendant when the joint is loosened for windingl orsetting. In addition, l preferably provide as above described, thesecond packed j ointbetween the `crown andthe opposed end surt'ace ofthe pendant.
